Filed: 1983-02-02
Abstract: PURPOSE:To prevent excessive injection of fuel, by selecting the decremental rate of fuel injection quantity increasing rate at the time when the engine temperatureis low such that it is increased as the temperature of intake air is raised. CONSTITUTION:At a step 102, a fuel increasing rate at the time when the engine temperature is low is determined by correcting a datum injection quantity of fuel on the basis of the output of a water-temperature sensor. At a step 108, an attenuation factor k1 corresponding to the temperature of intake air is obtained on the basis of the output of a sensor for detecting the temperature of intake air, and the fuel increasing rate is decreased by a value k1. By employing such a method, it is enabled to improve the engine performance at the time when the engine temperature is low, without causing increase of emission at the time when temperature is normal.
